On November 17, at the site of the Lunan natural gas deep treatment project in the Tarim Oil Field, efforts were in full swing to install the \"ChuanYuan Xinneng\" product – a propane refrigeration system process treatment module – which was developed by the Southwest Branch of the engineering construction company under CNPC Engineering. Known as a \"green refrigeration expert,\" this system boasts excellent properties such as energy efficiency, environmental friendliness, wide applicability, and strong resistance to fluctuations. It demonstrates the innovation capabilities of the Southwest Branch in the field of natural gas processing, and serves as an important achievement in advancing the green transformation of the energy industry. Propane refrigeration systems use propane, which is commonly found in our daily lives, as a refrigerant. This component derived from natural gas not only offers high cooling efficiency but is also very environmentally friendly, making it a truly eco-friendly tool in the field of natural gas processing. As a core component of the natural gas condensate recovery system, it enables improved dehydration and dehydrogenation efficiency through deep refrigeration, while also reducing the energy consumption of the project, thereby helping to enhance its performance and efficiency. At present, these system products are mainly used in refrigeration projects and are highly suitable for natural gas pretreatment processes. They play an important role in applications such as natural gas ethane recovery, natural gas liquefaction, and hydrocarbon and water removal, offering significant benefits in terms of energy savings, consumption reduction, and comprehensive resource utilization. The system consists of a refrigeration compressor, a propane heat exchanger, a propane economizer, as well as various associated containers and pipelines. The system delivered to the Tarim Oil Field this time includes 3 compressor units and 2 sets of process treatment modules; all of these modules have passed strict inspections by the China Classification Society, demonstrating the company’s comprehensive capabilities in providing complete refrigeration systems. This system not only has strong anti-interference capabilities and can adapt to various operating conditions, but also features low operating costs and easy maintenance, demonstrating good economic benefits. During the research and development process, the Southwest Branch formed a specialized team composed mainly of members from the New Energy Technology Research Institute and the Cryogenic Laboratory. This team tailored its efforts to each project, taking into account the project’s main manufacturing processes, and ensured strict control over the entire process from research and design to production, assembly, integration, and testing and delivery. Adopting a modular design concept allows for flexible combination, just like building with blocks, which not only ensures precise matching of the system but also significantly shortens the construction period. Digital intelligent control is also employed in the manufacturing process; from the arrival of materials to welding and shaping, each stage is under visual monitoring to ensure high product quality. Next, the Southwest Branch will work closely with all parties involved in the project to carry out on-site installation and commissioning tasks, thereby contributing to the early operation of the project and to the efficient development of resources in the Xinjiang region.
